Improvement in pumps

IMPROVEMENT IN PUMPS.

To all whom it may concer/n:

Be it known that I, SAML. S. DURBON, of Lebanon, in the county of Booneand State of Indiana, have invented a new and Improved Mode of PumpingVater from Wells; and I do hereby declare that the following' is a fulland eXact description thereof, reference being' had to the accompanyingdrawings, and to the letters of reference marked thereon, of which-Figure 1 represents a perspective view; Fig. 2, a lateral section; Figs.3 and 4, transverse sections; and Fig. 5, a detail.

The nature of my invention consists in building an air-tight iron boX,A, with three apartments. Two ot' them are for pumping and one forreceiving and exhausting. This exhausting-chamber is an air-chamber.

I insert into each oi the two pumping-apartments the tubular valve-seats6 6, to receive the gum-elastic valves 7 7 which are provided withspindles l1 11, and are confined to a perpendieularmotiou by means ofholes in the brackets 8 and 9 of the frame 10.

1S 18 represent two holes through the partition between thcair-chamberand the pumpingapartments, by means of which the water passes from thepu m pin g-apartments into the exh austing-chamber, (air-chairmen) wherethe pressure ot the air forces it out through the tube C.

13 represents a self-'adj usting leverage,which is provided with gulnvalves 15 15, and is so arranged as to close one or both holes, as thecase may require. This leverage slides in the frame 16 by means ol" aslot and bolt, 14. To the top of these pumping-apartments I attach twocylinders, B B, and provide each with a piston-rod, 4 4. To the lowerends of these piston-rods I attach a piston composed of three parts, 1,2, and 3. The conic-shaped washer 1 is fastened to the piston-rod 4, soas to meet the point of the conic-shaped washer 2, which is alsofastened to the piston-rod 4, but by means of a screw.

3 3 represent the gum-elastic packings, so shaped as to t the twoconic-sh aped washers tightly.

The piston-rods are provided with cogged segments H H, which play intothe cogs of the wheel G, creating' a rotary motion. This motion iscreated by the power at the pulley-wheel or crank M, which drives thecog-wheel N and works into the elliptic L. This elliptic is arrangedwith an eccentric, L to carry the driving-wheel to the proper gear.

0 represents the wrist ofthe elliptic and attachment ofthe extension ofthe piston-rod 4. Erepresentsaplatform. JJ arefriction-wheels.

Operation: When the pump is set in motion the little drivin g-wheel Nmoves between the eccentric L and the cogs of the elliptic L, forcingthe elliptic to a motion which raises or lowers the piston-rods 4, thecogs of which work into the cog-wheel Gr, creating a reverse motion onthe other piston-rod, so that when one piston-rod moves upward the othermoves downward. The pistons will, when raised, permit the water to forceitself into the pumpingapartments, and from there it will be forced intothe air or exhausting chamber by the lowering of the pistons. In thisway I create a continuous iiow of water.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

The tubular valve-seats 6 6, the spindle gum valves 7 7, theself-adjusting leverage 13, with valves 15 15, the self-adjusting gumpiston composed of 1, 2, and 3, andthe elliptic L,with the eccentric L',all arranged and operating substantially as and for the purpose setforth.
